BUTTER-PRINTING MACHINE.

SPECIFICATION forming part of Letters Patent No. 758,706, dated May 3, 1904.

Application filed July 11,1903. Serial No. 165,173. No model.

To all whom. it may concern: the partition is arranged a mold O, upwardly 5 Be it known that I, LAINER ALEXANDER open and having a sliding bottom C, the for- SHELDoN, acitizen of the United States, residward edge of this bottom fitting into a horiing at Lincoln, in the county of Lancaster and zontal groove formed in the inner face of the State of Nebraska, have invented a new and front wall of the mold, the rear wall of the useful Butter-PrintingMachine, of which the mold being formed by the partition and the following isaspecification. opening B permitting butter to be forced My invention is an improvement in butterfrom the platform B by the plunger B into operating machines. the mold. Sliding vertically within the mold IO The object of this invention is to devise a is a cutter (l sharpened on its lower edge and machine having a platform upon which the closing when in a lowered position the openbutter can be placed, from whence it will be ing B". The cutter is vertically slotted, and automatically carried into a mold, cut into a pin O carried by the partition, projects one, two, or more pound blocks, as may be into the slot and limits the movement of the I5 desired, pressed into the desired shape and cutter. Between the cleats in which the plunstamped with the imprint of any desired deger slides the platform B is cut out, and the 5 sign, and then ejected from the mold upon sliding bottom C of the mold fits in this cutwrapping-paper and conveyed by a traveling out portion. To actuate these various movbelt to a table, when the wrapping operation able parts, a shaft D is journaled in suitable 20 is completed by hand. bearings formed in blocks D, secured at the My invention consists of the novel features upper ends of the framework, and rigidly 7 of construction and combination of parts de mounted on the shaft is a drive-pulley D and scribed hereinafter, particularly pointed out a beveled gear I). Avertical shaftEis jourin the claims, and shown in the accompanynaled at the rear end of the frame and at its 2 5 ing drawings, in which upper end carries a beveled gear E, meshing Figure 1 is a perspective view of my printwith the beveled gear D and at its lower end ing-machine.

Fig. 5 is a plan view of forward end of the shaft D extends through a the under side of the platform, showing levertical board A, carried at the upper part of vers for operating the slide. the frontend of the frame. On theforward end In the construction of a machine embodyof the shaft D is a collar 1), carrying a double ing my improvement I employ an open framecrank-arm I), and to the rear of the crank-arm 35 work A, and adjacent one end of said framearoller-carrying arm I). A pitman F has a work is arranged a table and table-frame A, slotted upper portion working on the outer 5 over which travels an endless conveyer-belt cranked portion of the arm I) and at its lower A The belt runs over rollers A mounted end is pivotally connected to a stamping or upon suitable shafts A, journaled in a porprintingblock F. A second pitman G, slot- 4 tion of the table-frame. On the frame A, adted adjacent its upper end, fits over the inner jacent to and partially overlapping the table cranked portion of the arm D and is pivotally 9 A, is a platform B. Parallel cleats B are connected at its lower end to the cutter C arranged on and transverse to the platform Pivotally secured to the front of the board A" B, and between the cleats slide a plunger B are two arms H and Il,projectinginto thepath 45 A suitable vertical end partition B is carried of the roller-carrying arm I) from opposite at the forward end of the platform, and the sides of the board, the arm H lying below the lower central portion of the partition is cut roller and the arm H above it, so that when out, as shown at B, the opening being in engaged by the arm I)" the arms H and H alinement with the plunger B" In front of will be moved in opposite directions. An arm H is pivotally secured intermediate its ends on the board A above the arms H and H and is pivotally connected to these arms by links H and through the medium of these links and the arm H a uniform reciprocatory movement is given the arms H and H.

To the under side of the platform B are pivoted intermediate their ends levers J and J, the inner end of each lever being pivoted to the sliding strip or bottom C. Idle pulleys J 2 are secured adjacent the front edge of the platform, one on each side of the strip. To the rear of the free end of the lever J is arranged an idle pulley J To the front of the board A above the arm H is arranged a pulley J. A chain J is secured to the arm H and is passed over the pulley J 4 and down over one of the pulleys J and is then secured to the free end of the lever J. A chain J 6 is secured at its upper end to the arm H, is passed down over the other pulley J around the pulley J and its lower end is secured to the free end of the lever J. The shaft A at the end of the table-frame adjacent the frame A is extended through the latter frame. A pulley K is fixedly secured to this shaft, and a pulley K is similarly secured to the shaft D, and a belt K runs over these pulleys and transmits power from the shaft D to the shaft A", driving the belt A Power can be applied to the shaft D in any desired manner.

In operating my device the butter is placed on the platform B in advance of the plunger, which forces a certain quantity of it through the opening B*, the bottom strip 0 sliding in advance of the plunger. As a certain amount of buttersa v one poundis forced into the mold the cutter C is forced downward by the pitman G and closes the opening B*. The pitman F forces the stamping-block downward, compressing the butter in the mold and imprinting the desired design thereon, and as the design is printed the arm H is struck by the roller-carrying arm D, and through the medium of the chain J 5 and lever J the strip C is withdrawn from the mold and the butter forced-downward" out of the mold. Springs L and L aid in drawing the stamping-block and cutter upward, and the pitman E having withdrawn the plunger the apparatus is ready to mold and print another pound of butter. An operator stands at the front of the machine and places sheets of wrapping-paper on a supplemental table M below the mold, and as soon as the printed butter is forced from the mold and falls upon the wrapper it is laid upon the conveyer-belt and carried to the table A, which may be of any desired length, where it is caught by the other operators and the wrapping operation completed. The slots in the cutter and pitmen F and G permit adjustment, so that the size of the prints can be varied'and the butter be molded into one, two, or five pound blocks, as may be desired.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. A device of the kind described comprising a platform, a mold arranged in front of said platform, the rear wall of said mold hav-. ing an opening formed in it, a plunger sliding on the platform in alinement with the opening, a cutter sliding vertically in said mold adjacent the rear wall of the mold and adapted to close said opening, a stampingblock working in said mold, a movable-bottom in said mold, and means for actuating said plunger, cutter-block and movable bottom.

2. A device of the kind described comprising a frame, a platform, a plunger working across said platform, a mold arranged at the front of the platform and in the path of the plunger, a cutter working in said mold, a stamping-block working in said mold in unison with said cutter, means for opening the bottom of the mold during the descent of the stamping-block.

3. A butter-printing machine comprising a frame having a platform arranged therein, a mold in advance of said platform, a plunger adapted to force butter into said mold, a shaft carried by the frame, a double-cranked arm on said shaft, a stamping-block Working in said mold, a pitman pivoted to the block and adjustably secured to the crank-arm, a cutter working in the mold parallel with the stamping-block, a pitman pivoted at the lower end to said cutter and having its upper end adjustably secured to the cranked arm, and

means for rotating said shaft.

4. A butter-printer comprising a mold, a plunger, a cutter working in the mold, a stamping-block sliding vertically in said mold,

. a sliding bottom in the mold, a platform in LAINER ALEXANDER SHELDON.
